This plugin allows you to announce a message via the new Actionbar in the game, which will appear above your health and armor bars. One of the many useful aspects of the Actionbar, is that it disappears after a few seconds (which can be adjusted in the config/command) so it won't sit in the middle of your screen and annoy you. You can also set custom join- and firstjoin-messages (basically "Welcome to the Server"-Messages" which you can edit and animate as you like) to enable the %money%, %prefix%, %group% and the %suffix% variable you have to install Vault and any Economy or Group plugin you want
Another feature of this plugin is the Actionbar-Announcer, which allows you to time your Join-Messages and such, as you like! For example: you can animate a, let's say, Welcome!-Message and make it appear like every 5 minutes :) PS.: The time units are in "ticks" - so 20 ticks equal 1 second
Animated Actionbar (either in the Join/FirstJoin message or in the Autobroadcast)
